摘要
从冠心病发病率极低的女青年（１８～３５岁）中选取６７例正常者（平均年龄为２１．７４±４．４９），作为受试对象，观察高频心电图对冠心病的诊断特异性。若以六导组合导联中高频切迹数＞３为判断可能冠心病的临界标准，则高频心电图对可能冠心病的诊断恃异性为８２．０９％。假阳性率为１７．９１％，六导组合导联切迹均数为２．２０±１．７７（ｘ±ＳＤ）．十二导联高频切迹数为１０．４±４．３０（ｘ±ＳＤ）．高频切迹在导联中的分布：肢导联多于胸导联，并且Ｖ１、Ｖ２、Ｖ３导联多于Ｖ４、Ｖ５、Ｖ６导联。
This article studied the specificity of HFECG to diagnose coronary heart disease,taking as subject 67 normal female youth,whose ages were 21.7±4.5,selected from the lower most incidence of coronary heart disease,The specificity of HFECG to diagnose the possible coro- nary heart disease is 82.09%by use of notching numbers more than 3 notching critical standard. The rate of false positivity is 17.91%,The notching numbers in the 6 leads are 2.20±1.77,and in the 12 leads are 10.4±4.30.The distribution of notchings in limb is more than that in precor- dial leads and the distribution in V1,V2,V3 leads is more than that in V4,V5,V6 leads.
